Abstract

PURPOSE:To enable titled wear prevention using a simple means by providing sealing devices on the upper face of a bed, lower face of a slide, and the joint face of upper and lower hard plates. CONSTITUTION:Pressure of a compressed air source 17 is reduced by a pressure- reducing valve P and the air is supplied to an upper empty chamber on the oil tank 14. Then, pressure-reduced pressed oil is led to upper and lower hard plates 3, 4 and joint faces 10, 11 between a slide 2 and a head 1 to form oil films. At this time, O-rings 18, 19 prevent leakage of oil, and at the same time, prevent entry of water and scales from outside. Thus, by forming oil films on joint faces 10, 11, generation of rust is prevented, good lubricating condition is provided, and wear due to relative sliding between members caused by impacts in pressing and load applied successively to juxtaposed dies can be prevented.
